Up at dawn again for another short boat trip before breakfast. This time we visited the Pahuachiro Creek. The water here is very dark, a result of tannins from the vegetation along the bank. It is the start of the rainy season. This close to the equator it is hot and humid all the time. There are only really two seasons: wet and dry. At the peak of the wet season much of the forest is flooded. We could clearly see the high-water mark on the trees. A good two or three metres above the current level. This makes the jungle almost impenetrable. With a small canoe you can travel a short distance from the river course but it is slow and difficult.
The water in the main river is a chocolate brown colour because of all the silt it is carrying. Where the black water from the creek meets the main river the two types of water do not mix immediately but swirl around each other in intricate patterns. This is the place for the river dolphins. They hunt fish that have been confused in the merging currents. The dolphins use their echo location to hide in the murky, silt laden water and then dart out to catch the hapless fish. The Amazon River Dolphins are pink and have a bulbous head that is part of their echo location system. Slightly smaller are the Tucuxi dolphins which are grey and look a little like Bottlenose Dolphins. We saw both types but they are very hard to photograph. You need some sort of precognition to guess where they are going to pop up next.
After breakfast, we went for a walk. Every time we walked in the jungle, we were warned not to casually touch things, not to lean on the trees and to be careful where we placed our hands and feet. This is seriously important advice. Shortly after setting off, we were shown a judgement tree. This is a tree that has become infested by fire ants. The trunk is riddled with holes and few ants can be seen running around. However, if you bang the tree then loads of ants come out. Traditionally, bad people would be stripped and tied to the tree. The village shaman would then hit the tree with a big stick. This “judgement” could be fatal. Shortly after pondering this lethal tree I came across a fuzzy blob on another tree trunk. This turned out to be a mass of caterpillars. What I didn’t realise at the time is that these can be equally fatal. The caterpillars of the Lonomia obliqua moth possess a uniquely potent anticoagulant venom. Wikipedia says “A typical envenomation incident involves a person unknowingly leaning against, placing their hand on, or rubbing their arm against a group of these caterpillars that are gathered on the trunk of a tree. The effects of a dose from multiple caterpillars can be dramatic and severe, including massive internal hemorrhaging, kidney failure, and hemolysis. The resulting medical syndrome is sometimes called lonomiasis. Death may result, either rapidly or after many days following envenomation”.
At the end of the walk, we spotted a sloth. In typically sloth fashion it was hanging from a tree looked like an abandoned bag of wet fur. Photographing sloths requires patience. They do not move very much and it sometimes hard to determine where the sloth ends and the tree begins. Eventually this one did move and not only did I managed to get a picture of its face but I could also spot that it was carrying a baby.
After lunch, while we were all snoozing, the boat moved further up the river. Here was a small village where we had been invited to see the release of some turtles. The yellow-spotted river turtle is one of the largest turtles and has been on the endangered list for a while. It has been hunted for food and was also exceedingly popular as a pet in the USA. Fortunately, now some work is being done to protect the turtles. The villagers collect turtle eggs and then protect them while they hatch. Once the baby turtles’ shells have hardened, they can be released into the wild with a much better chance of survival. We arrived at the riverbank by the village to find buckets full of baby turtles, all ready to be set free. Diane loved this. She carefully carried a bucket to a marked area by the water and tipped them out. The turtles knew exactly what to do and headed straight down the slope for the water. It was great to watch.
